I have a friend that moved to Japan when he was in his twenties to work in a blue collar job. The pay was good, but he had to work a lot of overtime, sometimes 12, 14 hours. These jobs also often offered a place to live nearby the factory. Somehow it seems very similar to this, the difference is that he got an actual apartment and not this sad excuse for one.
One day he got sick of it all, so he started to just apply for these jobs, get free housing, and never show up to work. He could live rent free for a month, sometimes two in the time between getting fired and finally evicted. When that happened, he would move to a different city and then do it all over again.
In the meantime he was studying Japanese and doing side gigs. After doing that for awhile he landed a job as an English teacher in a school and he doesn’t have to do that anymore.
